Urine specimen collector

Abstract

Improved apparatus for combined collection of an exact fraction of each of a plurality of urine voidings in a common storage container. Provision is made for dividing each voiding into a small aliquot portion and a balance portion further provision is made for storing a plurality of said aliquots in common storage; and for discarding said balance portion in a convenient fashion.

What is claimed is: 
     
       1. An aliquot sampling apparatus comprising: an outer elongate container having an upper inlet and a bottom outlet port; an inner elongate container spaced from the outer container and concentric therewith to provide an annular chamber therebetween, said inner container having a bottom access port; resilient sealing valve means at the bases of said containers and connected thereto, said resilient valve means snapped into the base of said outer container; first and second outlet means, said inner container being adjustable in said valve means to position said access port for communication with the outlet port of said outer container in a first position of said inner container; and to position said access port in communication with said first outlet means in a second position of said inner container, said second position also positioning the outlet port of said outer container in communication with said second outlet means. 
     
     
       2. The apparatus of claim 1 which further comprises storage means connected to said first outlet means for directly accumulating a plurality of aliquots dispensed from said inner container. 
     
     
       3. The apparatus of claim 1, which further comprises cover means for covering said containers, said cover means being connected to the inner container, thereby operatively controlling position of said inner container and said valve means when cover is moved from a first uncovered position to a second covered position. 
     
     
       4. The apparatus of claim 3 which further comprises detent means to more positively locate said first and second positions. 
     
     
       5. The apparatus of claim 1 wherein said inner and said outer containers are so constructed as to enclose cross sectional areas at every level which are in generally constant proportion to each other. 
     
     
       6. An automatic urine aliquot accumulating apparatus for collecting a known pooled fraction of a series of unknown volumes of liquid comprising: an outer elongate container having an upper inlet and a bottom outlet port; an inner elongate container spaced from the outer container and concentric therewith to provide an annular chamber therebetween, said inner container having a bottom access port, said inner and said outer containers so constructed as to enclose cross sectional areas at every level which are in generally constant proportion to each other; sealing valve means at the bases of said containers and connected thereto; first and second outlet means; said inner container being adjustable in said valve means to position said access port for communication with said outlet port of said outer container in a first position of said inner container; and to position said access port in communication with said first outlet means in a second position of said inner container, said second position also positioning the outlet port of said outer container in communication with said second outlet means; storage means connected to said first outlet means for accumulating a plurality of aliquots dispensed from said inner container; and cover means for covering said containers, said cover means being connected to said inner container, thereby operatively controlling position of said inner container and said valve means when cover is moved from a first uncovered position to a second covered position so that in said first uncovered position valve means is automatically in said first position and in said second covered position valve means is automatically in said second position without additional operator attention.
